prising such solvents as alcohol and acetone,

with which evaporation retarding material has been incorporated, for the removal from a surface of previously applied finish, such, for instance, as varnish, paint, enamel, shellac, gums and lacquers. In preparing such removers or compositions of matter of this general character for removing varnish and other finish from surfaces, paraifin, alcohol and acetone may for example be combined in proportions suitable to accomplish the desired result. A remover consisting of pounds of parafiin, 135 gallons of alcohol and 137 gallons of acetone gives good results in practice when applied to the surface from which the finish is to be removed, thereafter removing simultaneously the dissolved finish and the remover from the sur face. The solvents, that is the alcohol and 'acetone in this composition, attack and dissolve the varnish or other finish while the parafiin prevents the evaporation and drying of the solvents before the remover has completed its operation. While parafiin is preferably used as the evaporation retard ing ingredient, which prevents the too rapid drying of the composition, other forms of wax or wax-like material may be used, such as a mineral wax includlng the hydrocar- =bons akin to paraffin, vegetable wax, such as carnauba, or animal wax-like material, such as beeswax or fatty acids. It is to be understood that the term wax is used in the broad sense to include any of the above specified waxes or wax-like materials 'or equivalent evaporation retardin materials.

The composition may be ma e in liquid form by placing the alcohol in the receptacle or mixing tank and adding the paraf fin or other a m retarding ingredient either- I in a melted condition the form of small particles after which the acetone-is added. The remover may also be made in the form of a semi-paste, in which case ceresin wax is used in addition to .theingredients comprised in the liquid form of remover. A suitable semi-paste remover for practical conditions of operation may comprise 40 pounds of paraflin, 40 pounds of" ceresin wax, 140 gallons of alcohol and 140 gallons of acetone. The semi-paste composition can be manufactured by first melting the p'araffin and 'ceresin wax together and adding them to the alcohol and acetone or the waxes may be dissolved in the alcohol.

Having thus described the invention in this application, which is a divisionalcontinuation of United States patent application, 162,885, filed June 24, 1903, which matured into Patent 1,014,211 on January.

9, 1912, to which referenceis made, in connection with a number of illustrative ingredients and formulas, to the details of which disclosure the invention is not, of course, to be limited, what is claimed as how and what is desired to be secured by Letters Patent is set forth in the appended claims;

1. The finish remover comprising approximately equal parts of alcohol and acetone with which several per cent. of waxy thickening material including parafiin has been incorporated thickening the remover to substantially semi-pasty consistency and effectively preventing excessive evaporation 10f the volatile material in the remover.

2. The substantially fluent finish remover consisting substantially of approximately equal parts of alcohol and acetone with which thickening material including paraffin has been incorporated increasing the consistency of the remover and eflectively retarding excessive evaporation of the volatile material in theremover.
